Riff Raff already trained with Hulk Hogan and joined forces with Katy Perry (when they dressed up like Justin Timberlake and Britney Spears). Now, the Neon Icon MC is teaming up with Justin Bieber for his next project.

“I’ve been working on that big album, Peach Panther,” Riff told TMZ Sunday, Jun. 14. “Drake might come through, [Lil] Wayne, Weezy. And I already got [Justin] Bieber on the album."

Surprised by the Riff/Biebs connection? You shouldn't be. They're actually old pals. Back in 2013, Diplo told a story about how Raff once broke Bieber's computer. Instead of getting mad, JB gifted the rapper with a Versace chain. You can watch that story unfold - in animated form - below.

And as you can see in this interview, Riff appreciated the present very much.

In August, the Neon MC promoted a track featuring Drake and Justin Bieber with production by Alchemist.

It's unclear if this is the song that's being discussed now. As reported in September, Riff released "Blue Jays" with Action Bronson over an Alchemist beat, but it didn't include Drizzy or JB. Could the new Biebs collab be a revamped version of this cut? Guess we'll have to wait to find out.

Peach Panther is set to be the follow-up to last year's Neon Icon, which features Childish Gambino, Mac Miller, Paul Wall and Slim Thug, among others. That album includes "How To Be The Man" and the viral sensation "Tip Toe Wing In My Jawwwdinz."
